Package Description

The class_loader package is a ROS-independent package for loading plugins during runtime and the foundation of the higher level ROS "pluginlib" library. class_loader utilizes the host operating system's runtime loader to open runtime libraries (e.g. .so/.dll files), introspect the library for exported plugin classes, and allows users to instantiate objects of these exported classes without the explicit declaration (i.e. header file) for those classes.

class_loader

The class_loader package is a ROS-independent package for loading plugins during runtime and the foundation of the higher level ROS pluginlib library. class_loader utilizes the host operating system's runtime loader to open runtime libraries (e.g. .so/.dll/dylib files), introspect the library for exported plugin classes, and allows users to instantiate objects of said exported classes without the explicit declaration (i.e. header file) for those classes.

class_loader VS pluginlib

class_loader is used in the implementation of the higher-level ROS package pluginlib which is the encouraged method for loading plugins in the ROS ecosystem. You should use class_loader when creating plugins intended for non-ROS packages and pluginlib when exporting plugins to ROS packages.

Quality Declaration

This package claims to be in the Quality Level 1 category, see the Quality Declaration for more details.

Usage

The interface is provided through two classes, class_loader::ClassLoader and class_loader::MultiLibraryClassLoader. Both provide similar interfaces but the former only binds to a single runtime library whereas the latter can associate with multiple libraries. The typical workflow is as follows:

  • Include class_loader/class_loader.h in your source code
  • Instantiate a class_loader::ClassLoader object passing the path and name of the library to open
class_loader::ClassLoader loader("libMyLibrary.so");

  • Query the class for exported classes which have an interface defined by some base class (MyBase in the example)
   std::vector<std::string> classes = loader.getAvailableClasses<MyBase>()

  • Create/destroy objects of said exported classes
 for(unsigned int c = 0; c < classes.size(); ++c)
 {
   boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
   plugin->someMethod();
   //'plugin' will automatically be deleted when it goes out of scope
 }

  • Destroy the ClassLoader object to shutdown the library.

Example: Basic Workflow for ClassLoader

#include <class_loader/class_loader.h>
#include "MyBase.h" //Defines class MyBase

int main()
{
  class_loader::ClassLoader loader("libMyLibrary.so");
  std::vector<std::string> classes = loader.getAvailableClasses<MyBase>();
  for(unsigned int c = 0; c < classes.size(); ++c)
  {
    boost::shared_ptr<MyBase> plugin = loader.createInstance<MyBase>(classes[c]);
    plugin->someMethod();
  }
}

0.3.6 (2016-10-24)

  • Made changes to two locking mechanisms inside class loader core\'s loadLibrary() function: 1) I added a lock to the \'addClassLoaderOwnerFor...\' function to protect it against a race condition with the unloadLibrary() function. 2) I also raised the loader lock to cover the whole function. Previously the check to see if a library is already loaded and the actual loading of the library was not atomic. Multiple threads could create shared library objects, for example.
